DHCP Setting Incorrect Gateway IP
I’ve had the Sagemcom Fast 5688W router for about three weeks. I’m fortunate to be near a tower and typically see 5 bars but noticed that I was getting 4 bars and just to see what would happen, I power cycled the router on 5/10/24. When the router rebooted, signal strength was good, but I could no longer connect to the internet from every connected device. Checking my IP settings I noticed the DHCP assigned gateway IP was 192.168.12.88 while the router’s management IP is still 192.168.12.1. For a test, I switched my PC to a static IP matching the DHCP assigned IP and switched the gateway IP to 192.168.12.1 and I was able to connect to the internet. Definitely a LAN DHCP settings issue as the WAN side is fine. Called into T-Mobile support and the rep was stumped and opened a ticket to investigate. As this will take a few days, I set static IPs on my devices so I can use the working gateway IP. I’m playing in the DHCP scope so I could see an IP conflict but should be ok until this is worked out as device use at my home is pretty consistent. Firmware is SGJi10205-1.2.B4 and I’ve only found one mention of this version so far over on Reddit while searching the internet for info. Post was from 18 days ago so this could be a relative new release and I didn’t see the issue until the power cycle occurred.
